SELF-LOCKING HINGE.

SPECIFICATION forming partof Letters Patent N 0. 598,647, dated February8, 1898.

Application filed June 10, 1897.

zen of the United States, residing at Ponghkeepsie, in the county ofDutchess andV State useful Improvements in Self-Locking Hinges forShutters and I do hereby declare the followingto be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to a novel form of selflocking hinge for shutters;and the object is to provide a simple and effective hinge whereby theshutter may be locked in an open or closed position and released onlyfrom the inside of the apartment. .i

To this end the invention consists in the construction, combination, andarrangement of the several parts of the device, as will be larly pointedout in the claims.

In the accompanying drawings the same of the invention.

Figure 1 is a perspective view of my improved s'elf-lockingshutter-hinge. Fig. 2 is a horizontal section of the same as it appearsin position with the shutter open and with the shutter closed, as shownin dotted lines. Fig. 3 is a vertical sectional view of the hinge andFig. 4 is a plan view of the hub of the hinged arm.

' l represents a bracket provided with an integral hollow arm 2 andavertically-alined integral lu g 3, formed with vertical parallel earsthe arm6, which is removably fixed in said lug 3 by the rivet 7. Theouter end of the arm 6 terminates in a vertical cylindrical socket S,and the outer end of the fixed arm 2 also terminates in a correspondingalined socket 9, and between these two sockets is mounted thecylindrical hub 10 of the hinged arm 11, which carries the shutter 12. j

13 represents a vertical spindle fixed in the sockets 8 and 9, and whichforms a journal for the hub 10 to oscillate on.

14 represents an integral lug on the under side of the arm 6, and itengages the ear 15 on the hub 10 when the shutter is closed, to

prevent the latter being raised or the arm 6 detached should the rivet 7be removed.

16 represents a lever fulcrumed on a rivet 17, fixed in the hollow arm2, and its longer `arm extends through the window-frame 1S andterminates in a button 19 on the inside of said frame. The shorter armof said lever 16 terminates in a pawl 20, which projects into the pathof a lateral pin 21, fixed on a bolt 22, having a vertical movement inan orifice v23 in the socket 9. rIhe lower end of said bolt isencompassed by a spiral spring 24, which normally presses said boltupward,

so that its projecting end 25 will engage one of the alined recesses 26,27, or 28 in the bottom face of the hub 10 and lock the shutter in aclosed or open position, ,as described. By raising the end 19 of thelever 16 its opposite end presses the .bolt 22 downward, so that its endis iiush with the upper plane face of the socket 9 and it isconsequently withdrawn from the recess in the hub 10.

The shutter may then be moved to the de- 27, and 2S, which correspond tothe position of the shutter .when it is closed, half-way open, andentirely open, it is evident that j additional recesses may be formed inthe hub 10e-as, for instance, one may be located between the recesses 26and 27-so that the shutter maybe bowed, if desired.

A shutter provided with a hinge of this character will be foundVpractically burglarproof when closed and will be found particularlyapplicable to all shutters located in exposed places.

Although I have specifically described the construction and relativearrangement of the several elements of my invention, I do not desire tobe confined to the same, as such changes or modifications may be made asclearly fall within the scope of my invention Without departing from thespirit thereof.

Having thus fully described my invention,

what I claim as new and useful, and desire to lOO secure by LettersPatent of the United States, is-

1. A hinge of lthe class described7 comprising the bracket 1, theparallel arms 2 and 6,

integral therewith, and the solid arm 6 detachably secured thereto, andprovided with the lug 14, and the vertical spindle 18 fixed in saidarms, in combination with the arm 11,

formed with a perforated hub 10 having the ear 15, whereby it is adaptedto be pivoted on saidspindle between the arms 2 and 6, and also toengage the lip 14, said hub being provided with one or more recesses 26,the vertical bolt 22, mounted in the arm 2, and adapted to engage saidrecess 26, and the lever 16 fulcrumed in said arm 2 and adapted tooperate said bolt, substantially as and for thepurpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
